Abstract
A regenerative peritoneal dialysis system includes a dialysis fluid loop; a filter located in the dialysis fluid loop, a first portion of the dialysis fluid sent to the filter rejected by the filter and returned upstream of the filter, a second portion of the dialysis fluid sent to the filter forming permeate, the permeate being rich in urea; and a urea removing apparatus located in the dialysis fluid loop downstream from the filter to receive the permeate and absorb urea from the permeate.
Claims17
A regenerative peritoneal dialysis method comprising:
- fluidly communicating a regeneration loop with a patient loop, the regeneration loop including a filter and a urea absorbing system;
- sending fluid to the filter located in the regenerative loop;
- rejecting a first portion of the fluid sent to the filter;
- returning the rejected first portion of the fluid upstream of the filter so that the rejected first portion of the fluid avoids the urea absorbing system;
- forming permeate with a second portion of the fluid sent to the filter;
- and
- absorbing urea from the permeate using the urea absorbing system.
